Another important application area for the Power Analysis software is determination of safe operating area for power devices. The software automates the process of displaying safe operating area for comparison to a given device’s specifications. Users can leverage the HDO oscilloscopes’ persistence mode to monitor safe operating area during critical events such as power-supply startup or changes in transient line or load conditions. A power-loss annotator identifies losses on all cycles in long captures. All loss measurements are calculated across all cycles with statistics.
